Definitions

  • the invention relates to a method and an apparatus for the automatic sidewise insertion of one or more cores of any desired length into the wedge formed by the supporting rolls of arborless winding machines.
  • the present invention has as its object to provide a method and an apparatus which simplify and accelerate the insertion of cores and thus minimize machine downtime.
  • This method in accordance with the invention permits the cores to be inserted in rapid sequence, control of the return stroke of the pusher to a position determined by the length of the next core to be inserted eliminating needless motion and hence waste of time.
  • a preferred apparatus for carrying out the method in accordance with the invention is characterized by a pusher adapted to move back and forth automatically along a feed track between variable end positions; by a transfer means, disposed parallel to the feed track, for the cores to be moved individually and successively, with their axes parallel, from the feed table to the feed track; and by a length-measuring means for the cores which is coupled to the transfer means, there being connected to the measuring means a control means which sets the particular end position during the return stroke of the pusher on the basis of the measured length of the core which is ready to be transferred.
  • the length-measuring means consists of a plurality of plates which are spaced from and parallel to one another and are mounted to be tiltable toward the feed track, and each of which in its end position operates a switch delivering a signal to the control means, a transfer means being provided which holds or releases a core, depending on the position of the pusher.
  • the cores to be inserted move successively from a feed table to the length-measuring means for transfer and are measured for their length before they are transferred.
  • the pusher then moves from its forward end position into a rearward end position which, based on the measured length of the core ready to be transferred, is just back of the latter's rear end.
  • the core is then released, moves onto the feed track, and is pushed sideways into the winding machine by the advancing pusher.
  • the pusher then moves back into a rearward end position which is determined by the measured length of the next core, now ready to be transferred.
  • the measurement of the length of the core serves as a signal for controlling the length of the return stroke of the pusher.
  • the transfer means releases the core as soon as the pusher has reached its rearward end position, and then immediately returns into its holding position in order to hold the next core delivered to it until the preceding core has been inserted by the pusher and the latter has returned into its end position.
  • FIG. 1 is a top plan view
  • FIG. 2 is a cross-sectional view taken along the line A-B in FIG. 1.
  • a feed table 1 Disposed on a feed table 1 with their axes parallel are a plurality of cores 2 but to random lengths. While one of the cores 2 is on the feed track 3 and is being pushed by the pusher 4, adapted to move back and forth in the directions indicated by the arrow P, from the side toward the wedge formed by the supporting rolls 5 of the winding machine, the next core 2 is ready for transfer in a transfer and length-measuring means.
  • the length-measuring means 6 consists of a plurality of plates 10 arranged side by side and mounted to be tiltable toward the feed track 3, and the transfer means 7 is formed by a plurality of swinging holders 11.
  • the transfer means 7 is in the holding position shown in FIG. 2, in which transfer of the core 2 to the feed track 3 is prevented.
  • the tipping of the plates 10 is brought about by the weight of the core 2" as the latter rolls over the hinge pin 8 of the plates 10.
  • the plates 10 operate a switch 9, such as a proximity switch, for example.
  • the pulses so triggered are applied to a control means.
  • the number of plates tipped, and hence the number of pulses fed to the control means, depends on the length of the core 2.
  • the latter controls the return stroke of the pusher 4 to such rearward end position that the pusher stops just back of the rear end of the core 2" which has been measured and is ready to be transferred.
  • the core 2" is released by the holders 11 as the pusher reaches its rearward end position and operates a limit switch, which triggers the release of the core 2".
  • the latter then rolls onto the feed track 3 and the holders 11 return into their holding position; and while the next core 2 is being moved to the transfer and length-measuring means 6 and 7, the pusher 4 pushes the core 2' located on the feed track 3 into the winding machine.
  • the apparatus in accordance with the invention is of simple construction, has a short overall length which need not exceed that of the longest core handles, and permits the rapid introduction of the cores into the winding machine.
